FUNCTION TESTING

A After performing any work on your firearm such as cleaning, disassembly, or installation of any accessory, check your firearm for proper functioning before firing any live ammunition.

1. Move the safety button fully rearward to the "ON" (SAFE) position.

2. Grasp the operating handle and pull the bolt fully rearward. It should lock in the open position.

3. With fingers and other objects clear of the ejection port, press the bolt release and allow the bolt to move forward under spring pressure. It should lock in the fully closed position. Repeat this procedure several times to check for free movement of the action assemblies.
